' applicati@ mea nay 1, 1926, serial Na The invention relates to anjmproved lock for use on doors of railway goods trucks, motorcars, motor cycles, cycles, window fastenings and the like.

The locking device of the lock takes the form of a bolt which passes right through the whole of the lock casing and projects at;

both ends. Inside the lock casing the bolt has 'mounted upon it a cylindrical sheath lo ,upon which l rotatable lockingdiscs are arranged, whic are provided with spring controlled pe members projecting through a recess on t e 'exterior of the casing. On the exterior of theaS'eanindicatiOn slot 'is' provided for the setting ofthe controlling num. ber for which ,the lockgis intended, the setv ting bein effected by turning the peg .members withgln slots provided for the purpose.

e numbers associated with the discs thus l become visible in succession vand each peg member` 1s moved selves are meanwhile kept under .tension whereby the pdis/cs are held firmlyxin their set position. After this setting has been elected a double lever controlled by a spring comes automatically into operation and engages through the medi/um of pins arran ed on- 1t in setting holes in the rotatable locking discs,

.30 the peg members of which are then returned to their positions of rest. The actuation of the double lever however also causes the withdrawal of a locking cam which enga es in the locking bolt, so that both the bolt an the lock can be moved relatively to one another. This opening of the` lock simultaneously causes a slide to move forward under the indication slot whilst, besides this the locking discs are engaged in an axial direction by a fork member rigidly connected to the locking :"bolt and are thus prevented from rotating.'

The bolt, which is controlled by a spring, -is thenfixed by means of a locking device.

InV order to put the lock into 'use the locking device is released again, whereupon the Vlocking bolt or the lock respectively iiies back into the locked position under the inluence of a spring. During this operation aprojectin arm carried by the locking bolt acts in suc., a manneron the double lever that'thev l 'ng cam again exgages the locking bo lst the -pins of t e double lever simultan "iisl emerge again from the locking discs, which latter are also now disengaged .from the fork.-

under the inliuence of the helical tension sprlngs into their original position, in. which the peg members once again project. The return movement ofthe slide member which covers theset lock number is retarded,

Constructional forms of the invention are illustrated by way of example in the accompanying drawings, Figs. 1 to 5, in which:

Veo

Fig. 4 is a detail showing the parts operadrical, isclosed. on the right and left handl sides by means of screw nuts which aresoldered, brazed or welded on. The locking bolt 4 passes through the middle of the lock and has-mounted upon it the partly lopen cylinder .5, which passes into thebroader cylindrical part 6. On the cylinder 5- several rotatable locking discs 29, 30, 31 and 32 are mounted in grooves or the like, these discs being provided with projectingrotatable adjusting peg members 39; whlch are under the influence of the helical springs 38. The peg members`39 project out in their end position through the slots 40 in a recess 12 of the casing 1 in such manner as to be oper'- able by hand. Each 'of the rotatable discs sus` 29-32 is-provided' atits-side with a setting I ring 33 marked with a scale of numbers, viz 1t-o9and0.4 .j i l,

This ring is held frictionally vonthe disc so as to allow of being adjusted for changing the -position of the number relative to the peg members.

In order lto open the lock vthe peg members 39 projecting in the recess 12 are pushed upwards successively going from left to r1ght, the correspondlng rotatable discs being carried with ythem in their motion. Since the pegs in moving upwards are subjected to increasing tensionthey are prefer- Iably turned round so as to lie transverse to the slots 40 and are pushed up over the exterior` edges of the latter. During this operation the numbers appear below the indication slot 11 in the casing, as shown for' example in Fi 1 for the'numbers 1, 2, 4, 8. The setting o the rotatable locking discs los 40 the fork ali-m (which areheld in position by the pegmem bers) in this tva to the key number of the lock, which is diierent for each individualI lock causes the pins 34 on the arm 17 of the 5 double lever 16, 17 which is pivoted at 18, to engage in the holes 35 of the rotatable locking discs 29-32, said holes being now in position immediatelybeneath said pins and the arm 16 of the double lever being pressed upwards by the helical spring 14 and so depressing the arm 17. Simultaneously the locking cam fixed to the arm 16 emerges from the bolt notch 9 and releases the locking bolt 4.

In the case of a padlock as shown in Fig.

, 1 Where thelocking bolt 4 engages in the end 3 of the shackle 2, the locking bolt 4, which is under the iniiuence of the helical Y spring 8 resting on-the ring 7, is drawn 20 back and locked in the open position by means of the click 13 engaging in the notch l1() of the locking bolt. As the lookin boltJ 4 is drawn'back the fork arm 22 which is attached to it also moves back together with the fork pins 2O and 21 mounted on'the said fork arm whereb the pins 'are guided into the holes 36 of t e discs 29-32. The operations are similar in the' case of the lock construction shown in Fig. 2, but in vthis case, if the lockin bolt 4 is immovably mounted; the lock as to be pushed over instead of the bolt being drawn back in order to effect the above mentioned operations and bring the lock into the fully unlocked positon in which it is held by means of the click 13. When thelock is in the fully unlocked position the fork arm' 22 will also have moved theslide I26, which is ro.

tatably pivoted at 27 and is pressed against 22 by a spring into the position in which they key number is covered.

y .The projecting peg memberswhich are still in the positions corresponding to the set-4 ting of their respective rotatable discs'are now turned .once again into positions longitudinal tothe slots 4Q and are thus caused to iiy back below the casing 1 under the action of' thehelical sprin 38.

. As is shown in Figs. 2 an i3, the rotatable locking discs 29, 30 and 31 are not only provided with adjusting holes forthe pins 34,

ut also with a numberv o f irregularly arranged so-called blind holes 35 having very little depth. These blind holes serve the PllPOSe of misleading unauthorized persons in any endeavour'to open the .lock and to render it impossible to iind the correct settin' holes.

y e locking disc 32, on the other hand, 50 has only one adjusting hole 35, which is preferably arranged in a somewhat recessed position, order to render it impossible for an unauthorizedV erson to findthesettin hole on this disc y testing out by'hand. ccording to the preceding arrangement it is essential that "the owner of the lock should set the key number v:from left to right. In the event of the setting havin been effected in the wron order, in Whic case the discs are at once ockedv by the engagement of the pins 34, it is possible to cause the locking discs to move back into their original position under the action of the helical springs 37 by depressing the arm 16 of. the double lever` by means of a thin 75 object introduced through the oiling hole 41.

In order to close the lock the `click 13 is released and the locking bolt 4 flies back into the locked positionV or if the locking bolt is immovably mounted, the lock moves into the said position Vunder the influence of the spring 8. lDuring this operation the fork pins 20 vand21 connected with the locking bolt 4 f'rst moveback out of the openings 36 of the locking discs 259-32. The projecting arm 23 connected with the locking bolt 4 through the medium of the fork arm 22 simultaneously moves and causes its cam 25, which has been brought into the position of engagemeint from its otherwise non-engagin posiltion by means of the spring 24, to sli e over the lever arm' 16 and, in assin the cam 19 of the arm 16, to ress t e loc "ng cam 15 back into the notc 9 of the bolt with the result that the lever arm 17 with its pins 34 comes out of engagement with the setting holes 35 of the locking discs 29-32, the latter being meanwhile moved back into` their original position by the action of the helical springs 37. Besides this the slide 26 is again pushed back by the contactof the fork arm 22 with the projection 28 and exposes the indication slot 11 `for ie-settin from left to right after the key number o the lock has already become invisible. The key number of the lock depends'upon the adjustment of the number of rin 33 car ried by the rotatable discs 29-32 which rings can, if necessary, be altered to anew number, y

When the shackle -2 shownon Fig. 1 is omitted the lodi constructed in accordance with Fig. 2 can be employed for a large number of different urposes', as mentioned above, It is especia y a plicablein cases 115 where the'lock itself or. t e lockin bolt 4 is rigidly attached to the object which is to be locked. The details ofconstruction may be varied in numerous ways without departing from the scope of the invention.

I claim:

1. In locks the combination of: a casing havin a-recess and slots termed in the wall of sai recess, with afspring controlled locking bolt passing through said casin a c lindrical member mounted on said loc 'ng olt, rotatable locking discs mounted on said cylindrrical member and having peri heral setting holes and so-called blind ho es, helical 130.

tension springs controlling the rotary movement of said locking discs, means for engaging said setting holes When said looking bolt is in the unlocked position and releasing said setting holes when said 'locking bolt is in the locked position, adjustably mounted setting rings fixed to said locking discs and peripherally marked With numbers, and rotatable s ring controlled peg members fixed on said iscs and serving for the set-ting and holding in position of said discs, said peg members passing through said slots andbeing operable by hand from the exterior of the casing` sulistantially as described.

2. In locks, the combination of: a casing having a recess and slots formed in the Wall of said recess, with a spring controlled locking bolt having a notch and passing through said casing, a cylindrical member mounted on said locking bolt, rotatable looking discs mounted on said cylindrical member and having peripheral setting holes and so-called blind holes, helical tension springs controlling the rotary movement of said locking discs, setting rings mounted adjustably on said locking discs and peripherally marked with numbers, rotatable spring-controlled peg members fixed on said discsand serving for the settin and holding in position" of said discs, sai peg members passing through said slots and being operable by hand from the exterior of the casing, a spring controlled double lever, lockmg pins on one arm of said lever adapted ,to engage said setting holes, a lookin cam on the other arm of said lever adapte to engage said notch on said locking bolt, said'locking pins and locking cam serving for alternately locking and releasing said rotatable discs and -said locking bolt, a fork member, pins on said fork member engaging with and holding in position said locking discs when the lock is open, and a projecting arm on said fork member carrying a resiliently mounted cam, said locking bolt on the closing of the look drawing back said pins so as to release said discs and simultaneously locking itself by causing said resiliently mounted cam to depress said double lever and so brin said locking cam into engagement with sai locking bolt.

Tn testimony whereof I have hereunto set my hand.
